2014 Shenandoah P, Stuff On Both Sides

When I looked up DDD, for the life of me I cannot see how you can reliably tell the difference between it and a valuable error. And I looked at LOTS of photo examples, along with several author's descriptions on what key differences to look for. There was so much overlap in diagnostics, and so much differently-interpretable language used for the descriptions, I don't see how even the highest experts don't have fierce debates over some coins. I'm not talking about very clearcut ones like the Duke Ellington 'ELL' one. --That's very easy to see and it's also not one of a kind. But every error coin with a population of 'multiple' must have a first one discovered by somebody, so what happens when the cause of doubling is 'if-y'? I'm not trying to argue about my 'nothing' quarter; if everybody says it's from a deteriorated die I obvioiusly have no leg to stand on.
But can anyone tell me what details the see in my coin prove it's a DDD, and how it would look different if it had whatever more magical error that would make it valuable?
By the way, why IS whatever other kind of doubling treasured while DDD is not? Seems like a very silly distinction, and in fact many of the 'legit' doubling photos I saw were barely-detectible compared to DDD ones (some of those looked pretty WOW to me). At least wrong-planchet coins make for kind of a cool story, as do coins that are rare because of some historical perspective, but "this malfunction" versus "that malfunction" occurring in a machine seems utterly arbitrary.

I forgot to ask, what could have caused that slash through the U in QUARTER? Also both A's in QUARTER and DOLLAR have a weird arc doubling inside the enclosed triangle. What causes that?

Those arc shaped areas are seen as a result of Die Deterioration.

I don't know if you read this link yet,it tells about all types of doubling http://koinpro.tripod.com/Articles/...Doubling.htm
I am going to ask one of our top pros to comment,Mike Diamond.

Bah, that's the main site I was looking at the other day when I said I can't see consistent differences between valuable and worthless doubling (in fact I can't see any doubling at all on a couple of the supposed valuable ones).
So does anyone want to take a crack at my question about WHY some doubling errors are valuable and others are worlthless? Like why is one kind of accident 'cooler' than another?

Now that top ^ 1955 one looks great and there's no way anyone could miss it. But that website also includes ones that look no more impressive or clear than that bottom 1955 (the DDD one).

Like this:



And this one is hilarious, the author says this 'P' is "a nice example of a quadruple punched mint mark." LOL! WHAT? I could stare all day at it, even with it this hugely magnified and I just barely see how it's doubled, never mind quadrupled, and I can't see how you could know this is repeat-punched, not deteriorated die. I feel like either the biggest idiot or the kid who could see the Emperor wore no clothes.

Wow, you're not kidding. I've been wondering how one device/character could double but the one right next to it not. This stuff's crazy.

Thank you so much!
